Referring to fig. 1-4, the present invention provides a technical solution:
the utility model provides a lotion injection apparatus for gynaecology and obstetrics, including lotion bottle 2, lotion bottle 2 upside threaded connection has lotion bottle lid 1, lotion bottle 2 inside is rotated and is connected with stirring rod 3, stirring rod 3 right part fixedly connected with bevel gear A4, bevel gear A4 downside meshing is connected with bevel gear B5, bevel gear B5 below is fixed with even axle 601, even axle 601 runs through swing joint has fixing base 602, even axle 601 lower extreme is provided with gear 6, fixing base 602 keeps away from even axle 601 one end and lotion bottle 2 fixed connection, lotion bottle 2 inside left side lower extreme is provided with piston cylinder 12, it is provided with piston head A10 to slide in the piston cylinder 12, piston head A10 right-hand member is provided with piston rod A7, piston rod A7 right part passes lotion bottle 2 and extends to the outside and fixedly connected with piston handle A9, piston rod A7 rear wall inlays and is equipped with rack 8, rack 8 and gear 6 meshing connection, piston cylinder 12 left part lower extreme discharge pipe fixedly connected with injection tube 15, discharge tube 15 is big end type structure about the top is big end, discharge tube 15 inner wall butt joint has injection tube 19, injection tube 18B 18 and injection tube 18 outer wall fixedly connected with injection tube 18, injection tube 18B connects with injection tube 18, injection tube 18.
According to the invention, the piston handle A9 is pressed towards the left side, the piston handle A9 drives the piston head A10 fixedly connected with the piston rod A7 to slide towards the left side in the piston cylinder 12, so that the washing liquid in the piston cylinder 12 is extruded towards the left side, and the abutting plate B16 moves downwards under the influence of the pressure due to the increase of the pressure in the piston cylinder 12, so that the washing liquid flows into the injection tube 18, meanwhile, the rack 8 on the piston rod A7 drives the bevel gear B5 fixedly connected with the gear 6 to rotate, and the bevel gear B5 drives the stirring rod 3 fixedly connected with the bevel gear A4 to rotate, so that the washing liquid in the washing bottle 2 is stirred. When the piston handle B22 is pressed to the left, the piston handle B22 moves the piston head B19 connected and fixed to the piston rod B21 to the right, and the washing liquid is discharged through the through hole B2501 of the washing tube 25 connected to the connection hose 24. Specifically, the right wall of the piston head A10 is fixedly connected with a spring A11, and the spring A11 is fixedly connected with the lotion bottle 2. When the piston head A10 moves leftwards, the spring A11 is stretched, and when the piston handle A9 is released, the spring A11 contracts to drive the piston head A10 to move rightwards. Further, the right wall of the piston head B19 is fixedly connected with a spring D20, and the spring D20 is fixedly connected with the inner wall of the injection cylinder 18. When piston head B19 moves to the left, spring D20 is extended, and when piston handle B22 is released, spring D20 contracts and moves piston head B19 to the right. Furthermore, the left part of the piston cylinder 12 is of a cylindrical structure, the right part of the piston cylinder is of a semi-cylindrical structure, the outer wall of the piston cylinder 12 is fixedly connected with the lotion bottle 2, a through hole A201 is formed in the lower side of the left end of the lotion bottle 2, a spring B13 is fixedly connected to the left end in the piston cylinder 12, a resisting plate A14 is fixedly connected to the left end of the spring B13, and the resisting plate A14 is in butt joint with the through hole A201. . When piston head A10 is located at the left part of piston cylinder 12, the lotion in lotion bottle 2 flows into the right part of piston cylinder, and spring A13 presses against the pressing plate A14 to keep the pressing plate in a state of abutting against the through hole A201.
It should be noted that a plurality of through holes B2501 are formed on the cleaning tube 25, the left portion of the connection hose 24 is fixedly connected to the cleaning tube 25, the left end of the connection hose 24 is fixedly connected to the U-shaped elbow 2401, and the U-shaped elbow 2401 extends to the inner side of the cleaning tube 25. Because the left end of the connecting hose 24 is provided with the U-shaped elbow 2401, the flowing-out lotion can be effectively prevented from flowing back into the connecting hose 24, and the lotion in the injection tube 18 is prevented from being mixed to cause pollution.
The working principle is as follows: when the device is used, the lotion bottle cap 1 is unscrewed, the mixed lotion is poured into the lotion bottle 2, the lotion bottle cap 1 is screwed to prevent leakage, the device is held, the piston handle A9 is pressed to the left side, the piston handle A9 drives the piston head A10 fixedly connected with the piston rod A7 to slide to the left in the piston cylinder 12, the lotion in the piston cylinder 12 is extruded to the left side, and the spring A11 is stretched. Due to the increase of the pressure in the piston cylinder 12, the abutting state of the abutting plate a14 and the through hole a201 is unchanged, and the abutting plate B16 moves downward under the influence of the pressure, so that the lotion flows into the syringe 18. When the piston rod A7 moves leftwards, the rack 8 drives the bevel gear B5 fixedly connected with the gear 6 to rotate, and the bevel gear B5 drives the stirring rod 3 fixedly connected with the bevel gear A4 to rotate so as to stir the lotion in the lotion bottle 2. The piston handle A9 is released, the spring A11 contracts to drive the piston head A10 to move rightwards, so that the piston rod A7 is driven to move rightwards, and the rack 8 drives the stirring rod 3 to rotate reversely to stir the lotion in the lotion bottle 2 again. And then the piston handle B22 is pressed to the left side, the piston handle B22 drives the piston head B19 fixedly connected with the piston rod B21 to move rightwards, the pressure in the injection tube 18 is increased, so that the abutting plate B16 and the discharge tube 15 are kept in an abutting state, the washing liquid flows into the cleaning tube 25 through the U-shaped elbow 2401 at the left end of the connecting hose 24 and is sprayed out from the through hole B2501, the piston handle B22 is loosened, the piston head B19, the piston rod B21 and the piston handle B22 are driven to move rightwards simultaneously by the stretched spring D20, the operation is repeated, multiple times of use can be carried out, when the device is used for the last time, the piston handle B22 is pressed to be kept still, the connecting hose 24 is pulled out from the injection needle 23, the piston handle B22 is loosened, the residual washing liquid in the connecting hose 24 and the cleaning tube 25 is discharged and sterilized, and the device is stored separately.
The foregoing shows and describes the general principles, essential features, and advantages of the invention.
